Transfer Pricing for Owner-Managed Cross-Border Companies

Transfer pricing governs the prices charged between related companies in different countries — a U.S. company paying its owner's Canadian company a management fee, a subsidiary licensing software from its parent, one entity lending to another. Each country requires those prices to match what unrelated parties would agree, so profit isn't shifted to where tax is lowest. The rules apply to a two-person group as fully as to a multinational.

What transactions does it cover?

Anything of value moving between related entities across a border:

• Services — management, administration, consulting, shared employees.
• Goods — inventory sold from one company to the other.
• Intangibles — software, trademarks, customer lists, know-how, licensed or transferred.
• Financing — intercompany loans, guarantees, and the interest on them.
• Cost sharing — jointly developed assets.

In an owner-managed group the common pattern is one company doing the work and another holding the clients, with a fee flowing between them. That fee is a transfer price.

What does arm's length mean in practice?

That the price could be defended as one a stranger would pay. For services, that usually means cost plus a modest markup for routine work and more for high-value work. For intangibles, a royalty comparable to third-party licenses. For loans, an interest rate a bank would charge a borrower of similar standing. The U.S. rules (Section 482) set out methods — comparable uncontrolled price, cost plus, resale price, profit-split, and transactional net margin — and require the "best method" for the facts. Canada, Germany, Israel, and most countries apply materially the same standard under OECD guidance.

Why does it matter if I own both companies?

Because each country audits its side. If the U.S. company pays its foreign affiliate too much, the IRS can reallocate income back to the U.S. and assess tax and penalties; if it pays too little, the other country can do the same in reverse. The owner can be taxed on the same profit in both places with no credit that fully fixes it. The exposure grows with the size of the flows, not the size of the companies.

What documentation is expected?

• Intercompany agreements in writing, signed before the transactions, setting out the services, goods, or rights, and the pricing basis.
• A transfer pricing analysis showing how the price was set and why it is arm's length — comparables for larger flows, a reasoned cost-plus memo for routine services in a small group.
• Invoices and payment records consistent with the agreements.
• Country-specific forms: in the U.S., related-party transactions are reported on Form 5471 or 5472 schedules; Canada requires its own reporting form above a threshold, with contemporaneous documentation to avoid penalties.

Documentation prepared before filing is what converts a penalty exposure into a defensible position.

What are the penalties?

In the U.S., a 20% penalty on underpayments from substantial valuation misstatements, rising to 40% for gross misstatements, with documentation prepared in advance as the main defense. Canada imposes a penalty of 10% of the adjustment when contemporaneous documentation is missing, above a threshold. Other countries vary; most follow the pattern of penalizing adjustments more heavily where no documentation exists.

How does this apply to a one-owner U.S.–Canada structure?

A Canadian corporation and a U.S. LLC owned by the same person, with the Canadian company billing the U.S. one for services (or vice versa), need an agreement, a cost-plus basis for the fee, and consistent invoicing. The U.S. side reports the related-party payments on Form 5472 (for a foreign-owned U.S. company) or Form 5471 (for a U.S.-owned Canadian company); the Canadian side reports under its own rules. Set up correctly at the start, it is routine; set up as "I'll move money when I need it," it is an audit waiting to happen.
